Nesting site of peregrine falcons

The painting was performed by A. N. Komarov on commission of A. F. Kots for the section “Evidence of evolution” on the subject “Problem of a species in terms of the variability of hunting birds.” Three paintings had been planned: “A nesting site of peregrine falcons”, “A nesting site of eagles”, and “A nesting site of goshawks.” The paintings were supposed to demonstrate the similarity of plumage in young birds, which, according to A. F. Kots, proved that “they all are descendants of a single species that had this sort of attire with lengthwise ornaments.”
